Patent number: 11619013Abstract: A milling machine may have a frame extending along a longitudinal axis and a milling drum attached to the frame. The milling machine may have ground engaging tracks that support the frame, and height-adjustable leg columns connecting the frame to the tracks. The milling machine may also have an engine for rotating the milling drum and propelling the ground engaging tracks. The milling machine may have a slope sensor to measure a roll angle of the frame, a speed sensor to measure a ground speed, and a configuration sensor to measure a machine configuration parameter. The milling machine may also have an alarm device and a controller. The controller may determine a threshold roll angle based on the machine configuration parameter, compare the roll angle with the threshold roll angle, and activate the alarm device when the roll angle is greater than or equal to the threshold roll angle.Type: GrantFiled: September 30, 2021Date of Patent: April 4, 2023Assignee: Caterpillar Paving Products Inc.Inventors: Nathan L.
